In a groundbreaking discovery, scientists in the U.S. have identified a previously unknown group of microbes thriving deep underground—up to 70 feet beneath the surface. This newly classified microbial phylum, named CSP1-3, not only survives in these harsh subterranean conditions but also plays a significant role in purifying groundwater, with exciting implications for future water filtration technologies.

The study, led by Dr. James Tiedje, university distinguished professor emeritus and director of the Center for Microbial Ecology at Michigan State University (MSU), uncovered CSP1-3 in soil samples collected from Iowa in the U.S. and China. Both sites belong to Earth’s Critical Zone, a vast region that stretches from the tree canopy down through soil layers to bedrock, sometimes extending as deep as 700 feet.

Humans have exceptional eyesight—better than most creatures in terms of color range, detail, and distance. But eyes evolved to handle life in jungles and prairies, not a world shaped by urban warfare, global tensions, and climate change. Today’s complex challenges demand the ability to see more, see faster, and see better. That’s why the United States is leaning into a new era of remote sensing—one driven by powerful commercial space imagery.

This revolution is fueled by advances in satellite technology and the plummeting costs of space launches. Companies are racing to equip spacecraft with next-generation sensors that can capture high-resolution images of Earth more frequently, affordably, and with greater clarity. At the forefront of this movement is Maxar’s WorldView Legion satellite platform, featuring cutting-edge imaging instruments designed by Raytheon.

A groundbreaking collaboration between Graz University of Technology (TU Graz) in Austria and the Vellore Institute of Technology (VIT) in India has resulted in the development of a 3D-printed skin model designed to replace animal testing in the cosmetic industry. This innovation aligns with increasingly strict European regulations—such as Directive 2010/63/EU—which significantly limit the use of animal testing for cosmetic purposes.

At the core of the research are specially engineered hydrogels, which serve as the foundation for creating lifelike, biomimetic skin structures. These hydrogels are infused with living skin cells and processed using a biocompatible 3D printing method. Their high water content makes them ideal for supporting cell growth and proliferation, but it also presents unique challenges in maintaining mechanical and chemical stability. To address this, TU Graz developed innovative crosslinking techniques that stabilize the structures under mild, cell-friendly conditions, avoiding substances that could damage the delicate cells.
